We consider the Pure Safe Ambient Calculus, which is Levi and Sangiorgi's Safe Ambient Calculus (a variant of Cardelli and Gordon's Mobile Ambient Calculus) restricted to its mobility primitives, and we focus on its expressiv- e power. Since it has no form of communication or substitution, we show how these notions can be simulated by mobility...

In the first part, we define a new programming language with a functional core and generalised recursion, by using Boudol's type system with degrees to rule out unsafe recursions. The language is extended first with recursive records, then with mixins, allowing the programmer to fully mix functional and object-oriented paradigms. We also...

Current software and hardware systems, being parallel and reconfigurable, raise new safety and reliability problems, and the resolution of these problems requires new methods. Numerous proposals attempt at reducing the threat of bugs and preventing several kinds of attacks. In this paper, we develop an extension of the calculus of Mobile...
